"Curtain Falls" is a song by English boy band Blue. It was released on 8 November 2004 as the first single from their first greatest hits album, Best of Blue (2004). The song was co-written by the band and Stargate and produced by Stargate. The background music is almost identical to that of Coolio's 1995 hit, "Gangsta's Paradise", as they both share usage of a sample of Stevie Wonder's "Pastime Paradise". When released as a single, it peaked at number two in Italy, number four in the United Kingdom and number eight in Germany. In France, the song was re-recorded in French and re-titled "Quand le tideau tombe"; although it was released as a single there, only the English version charted.
